Types of Precision Resistor Manufacturers

Whether you are looking for thin film or foil resistors, you can find several precision resistor manufacturers to choose from. These resistors are used in a wide range of applications, including aerospace, military, industrial, defense, medical, and communication. Compared to ordinary resistors, these precision resistors are more durable and accurate. They also meet higher standards in load life and resistance value tolerance.

The most commonly used resistor technology for precision resistors is the foil resistor. These Riedon precision resistors are manufactured using special alloys and stress compensation methods to achieve nearly zero temperature drift. This resistor is considered to be the most accurate resistor on the market. These resistors are used in the most demanding applications.

Precision foil resistors are manufactured by attaching a metal foil with known characteristics to a special ceramic substrate. The metal foil is then etched by a laser. Once the resistor is etched, it is then laser-trimmed. These resistors are used in applications that need high precision and low noise.

Another type of resistor that is available in the market is the thin film chip resistor. This type of resistor is used in humid and polluted environments. It is a ceramic substrate that is covered with a thin layer of silicon. It comes in a variety of capacities, from 0.25 to 0.33 W. Moreover, these resistors have anti-sulfur terminations. They are also available in a variety of other specifications.

Thin film resistors are cheaper than wire wound resistors. They are also more space-efficient. However, they will oxidize when exposed to high temperatures. They are also easily affected by ESD. This makes them less stable than wire wound resistors. In addition, this resistor type does not have the same accuracy as foil resistors.

The thickness of the resistor also has an impact on the resistance value. Thick film resistors have higher resistance values, but they tend to drift to small values in high-voltage environments. The thickness of the resistor can be adjusted to reduce the drift. However, this type of resistor is only used in higher-end products. They can achieve 0.001% accuracy.

A wire-wound precision resistor is also used in a high-voltage environment. This type of resistor is used in applications such as electric cars and high-speed trains. It also has good thermal stability. Compared to the thick film resistor, this resistor has a small temperature coefficient. It is packaged in silicone resin.

Other types of precision resistors include wire-wound, metal film, and oil-filled resistors. These resistors are used in applications such as microelectronics, motor speed control, and communications. They are also used in commercial and military applications. They are also RoHS compliant.

Thin film chip precision resistors are also available in a variety of capacities. The resistance values can be adjusted using a cutting-off method. In addition, these resistors can be manufactured in a variety of materials. These resistors are used in applications for audio, preamps, and amps.

The resistors offered by these manufacturers have a variety of features, including a working temperature range of up to 150 degrees C. These resistors can also be used in dynamic braking applications. In addition, these resistors have a four-pin structure that facilitates precision sampling. The resistors also have an auxiliary radiator that enhances the stability of the sampling resistor.
